Aim To find out substance A, B, C, D and E
Hypothesis: We think that A is cornflour B is salt C baking soda D is cream of tar tar E icing sugar
Results A-Cornflour B-Salt C-Baking soda D-Icing sugar E-Cream of tartar
Equipment Iodine litmus paper Baking soda Salt Icing sugar Cream of tartar Cornflour Beaker vinegar spoon
Explanation Vinegar makes baking soda go fizzy because These two products react even though we consume them they still have a chemical make up and vinegar is a very volatile acid so when mixed with the Alkenlined Baking soda it reacts volatily an that is why vinegar makes baking soda fizz.
12/05/11 Aim: To find the correct substance out of a,b,c,d and e
Hypothesis: A: cornflour B: salt C: baking soda D: cream of tartar E: icing sugar Because we examined them all by smell and look
Method:
Put the substances one at a time in the beaker with a drop of water or vinegar
We got the substances in the beaker
Results: Method:
1. Gather samples of pens.
2. Draw a line across a strip of filter paper, 1-4cm from the bottom.
3. Attach to straw with masking tape.
4. Put filter paper in beaker, making sure the ink is at least 1-2cm above
the water.
5. Observe.
6. Remove filter when water has travelled about 3/4 of the way up the strip.
7. Compare results with the ransom note results.
Results -
Conclusion -
The _ pen wrote the ransom note because Gravity free water There is no air in the glass so the pressure on the out side keeps the water In the glass and the cardboard on the out side. Its like when you put a cup on your mouth and suck really hard. Color Disc Spinning Top
The Color Disc Spinning Top works by the spinning motion making it look like the colours Are mixing and forming another colour witch in this case is a sort of white colour
#1.aim/question
All experiments always start with a question and The whole aim of the experiment Is to find the answer to the question
Aim: what metal conducts metal the fastest steel aluminum grass
Hypothesis:estimation I think that steel will be the fastest conductor of heat because steel would probably be the slowest to melt but will trap the heat.I think that aluminum will be the slowest conductor of heat because it will probably just melt.
Method:variables Controlled variables:things you will control Environment e.g:no wind no rain Type of wax Heat Manipulated variables:things you will change
Observation: Does it have a smell,taste,felling and
Materials:list of supplies you will need
Procedure:detailed step by step description of how you conduct your experiment
Method: Procedure: 1. We put small pieces of wax in the hollows on the ends of 4 strips of different metals that were fixed on a round wooden frame. 2. We heated the metal strips. 3. We timed the melting of the wax.
We recorded the times in a table.
Results: The wax melted in the following order:

Our Group found that the wax melted in the following order: 1st_ 2nd _ 3rdLast _
The class average: 1st_ 2nd _ 3rdLast _
Conclusion: On Average the wax melted in the following order: 1st_ 2nd _ 3rdLast _. We noticed that................happened.
The wax melted fastest with thebecause the molecules are easer to move than in the other metals and this is what makes the heat travel through the metal. This is called “heat conduction”. Where the molecules are more difficult to move, heat takes more time to move through it.
Conduction occurs when the molecules bump against each other and cause more movement. It is like pushing someone who trips and pushes another person in a crowd and the movement ripples outwards.
We use copper metal in_ because we want heat to_; we use steel in so that heat doesn’t_. Brass is used in taps because. Aluminium is used in pots because_. All of these metals do get hot after a while such as_.
Plumbers/engineers/sheet metal workers usebecause it is easy/hard to transfer heat. This is good/a problem because_.
Cooks preferbecause_, however they need to be careful that food may burn.
A welder uses _ to braise metal because it is easy to melt but the welder is made of which gets hot but not too hot. Science Fair Due Friday 3 June Week 5
This table is different from the one outlined in the above Science Fair booklet.
